The short version

Carry-on the essentials: travel documents, medications, and anything you need before your checked bag reaches the cabin.
Pack a mix of casual daywear, swimwear and at least one smarter outfit for evening; check whether your ship has a formal night.
Bring things ships often do not provide: a power bank, a lanyard for your key card, motion-sickness remedies and any specialty toiletries.
Know the rules: no irons or extension cords with surge protectors, and alcohol/beverage limits vary by line.
Leave room for what you bring home, and pack light. Cabins and storage are compact.

Your carry-on (the do-not-lose bag)

On embarkation day your checked luggage is delivered to your cabin later, sometimes a few hours later, so anything you need right away goes in a carry-on you keep with you:

🪪

Documents & ID

Passport or birth certificate plus photo ID, booking confirmation, and any visas. Do not pack these in a checked bag.

💊

Medications

All prescriptions in their original packaging, enough for the whole trip plus a few spare days.

👙

Day-one basics

Swimwear and a change of clothes so you can enjoy the ship before your bags arrive.

🔌

Chargers & a power bank

Cabins have limited outlets; a power bank and a USB charger earn their space.

Clothing: day, evening and dress codes

Days are casual, resort wear and swimwear. Evenings step it up a little, and many ships still hold one or two smarter or formal nights on a weeklong sailing. Pack:

Casual daywear and comfortable shoes for ports and decks.
Swimwear (two if you can, so one can dry).
Smart-casual evening outfits, plus one dressier option if your ship has a formal night.
A light jacket or layers, even in warm regions, indoor air-conditioning is cool.

Dress codes vary by line and ship. If a formal night matters to you, confirm what your sailing does before you pack the tuxedo or the cocktail dress.

What not to pack (the rules)

Most lines prohibit irons and steamers (fire risk), and surge-protector power strips. Cabins usually have limited outlets, so a simple non-surge USB strip is the safe choice if allowed. Alcohol and beverage limits vary a lot by line, so check yours before you pack drinks.

Also skip anything sharp, candles, drones (often restricted), and hoverboards. When in doubt, the line's website lists prohibited items, and a specialist can confirm the current rules for your ship.

The bottom line

Carry on your documents, medication and day-one basics, pack a mix of casual and one smarter outfit, bring the small things ships do not provide, and leave the prohibited items at home. Do that and embarkation is a breeze.

Frequently asked questions

What should I pack in my cruise carry-on?

Anything you need before your checked luggage reaches the cabin: travel documents and ID, all medications in their original packaging, swimwear and a change of clothes, chargers and a power bank. Never check your passport or medication.

What is the dress code on a cruise?

Days are casual (resort wear and swimwear). Evenings are smart-casual, and many ships hold one or two dressier or formal nights on a weeklong cruise. Codes vary by line and ship, so confirm what your sailing does.

What is not allowed on a cruise?

Most lines prohibit irons and steamers, surge-protector power strips, candles, sharp objects, and often drones and hoverboards. Alcohol limits vary by line. Check the line's prohibited-items list before you pack.

Do cruise cabins have enough electrical outlets?

Usually only a few, so a power bank and a non-surge USB charging strip (if your line allows it) are worth packing. Do not bring surge-protected power strips, they are commonly banned.

Should I pack a formal outfit for a cruise?

If your ship holds a formal or smarter night and you want to take part, yes, pack one dressier option. Otherwise smart-casual evening wear is plenty. Confirm your sailing's dress nights before you decide.
